Which of the following efficiency types refers to the measurement of water that is delivered to the farm gate from the source as a percentage of water released from the reservoir?

Explanation:

Water Delivery Efficiency

Water delivery efficiency measures the effectiveness of water transport from the reservoir to the farm gate. It is essential to understand this concept to ensure optimal water usage in agriculture. This type of efficiency is critical in irrigation practices to minimize water loss and ensure that the maximum amount of water reaches the crops. The different types of efficiencies related to water delivery are:

• Conveyance Efficiency: This refers to the measurement of water delivered to the farm gate from the source as a percentage of water released from the reservoir. It accounts for the losses that occur during the conveyance process, such as seepage, evaporation, and leaks.

• Application Efficiency: This measures the efficiency with which the delivered water is applied to the crops. It focuses on the water used by the plants versus the water delivered to the field.

• Distribution Efficiency: This measures how evenly the water is distributed across the field. It looks at the uniformity of water application.

• Field Water Use Efficiency: This measures the crop yield per unit of water used in the field. It is a comprehensive measure that includes both the efficiency of water delivery and the effectiveness of its use by crops.

Analyzing the Given Options

1. "Conveyance Efficiency" (Correct Answer)

   • This option correctly identifies the type of efficiency that measures the water delivered to the farm gate from the source as a percentage of water released from the reservoir. It accounts for the losses during conveyance.

2. "Application Efficiency" (Incorrect Answer)

   • This option refers to the efficiency with which the delivered water is applied to the crops, not the conveyance process.

3. "Distribution Efficiency" (Incorrect Answer)

   • This option measures the uniformity of water distribution across the field, not the conveyance process.

4. "Field Water Use Efficiency" (Incorrect Answer)

   • This option measures the crop yield per unit of water used in the field, which is a comprehensive measure but not specific to the conveyance process.
